Effect of Sauropus androgynus leaf extract, fish oil and vitamin E on performance, egg quality and composition in laying hens
Abstract: The objective of
this study was to obtain enriched eggs with low cholesterol content.
Forty-eight laying hens (strain Dekalb Warren) aged 72 weeks were distributed
into six treatment groups as follows: 1) Laying hens fed diet without Sauropus
androgynus leaf extracts (SALE), fish oil and vitamin E (P0) as the control; 2)
Laying hens were fed diet with 27 g SALE/kg diet, but without fish oil (P1); 3)
Laying hens were fed diet with 27 g SALE/kg diet, 1.5% fish oil (P2); 4) Laying
hens were fed diet with 27 g SALE/kg diet, 1.5% fish oil and 60 mg vitamin E/kg
diet (P3); 5) Laying hens were fed diet with 27 g SALE/kg diet, 3% fish oil
(P4); 6) Laying hens were fed diet with 27 g SALE/kg 3% fish oil and 60 mg
vitamin E/kg diet (P5). Experimental results showed that the treatments
affected (P <0.05) egg production, thick eggshell, egg white height, yolk
color, the odor of eggs after the split (P <0.05). It was shown that the
treatments had no effect on the contents of protein, fat, β-carotene of eggs
but affected the contents of cholesterol and vitamin E of eggs. In conclusion,
the treatments improved egg quality and increased egg Vitamin E but reduced egg
cholesterol.
